DATING-STAMP.

Specification of Letters Patent.

Patented Mar. 13, 1917.

Application filed November 20, 1915. Serial No. 62,477.

To all whom it may concern:

Be it known that T, CHARLES S. ELLrs, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dating-Stamps; and hat the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in dating stamps, and the invention consists in the combination and arrangement of the parts shown in the drawings and described in the specification, and is pointed out in the appended claims.

Among the objects of the invention is to provide a novel dating stamp provided with a casing which incloses the printing members except at the printing line, whereby the inked printing members are prevented from coming in contact with the fingers of the operator and which. also prevents the ink on the printing members being transferred to papers or other objects on which the stamp may be laid.

A further object of the invention is to provide a casing for a stamp of this general character so constructed and arranged as to afford access therethrough to adjusting devices for the printing members, whereby the type may be composed at the printing line.

A further object of the invention is to provide an improved casing or shell for dating and like stamps so constructed and arranged as to be readily assembled and interlocked in the complete stamp without the necessity of employing special fastening means.

The stamp herein shown, and constituting one embodiment of my invention, is a familiar form of band stamp and the inclosing casing is slotted for the passage of notched flanges on the bandwheels, which flanges serve as means to adjust the type of the stamp.

In the drawings: I

Figure 1 is a side elevation of a stamp embodying my invention.

Fig. 2 is an end View thereof.

Fig. 3 is a cross section on the line 3-8 of Fig. 1.

Fig. 4: is a perspective view of one member of the inclosing shell or casing.

Fig. 5 is a perspective view of the bridge and 11 the hand piece.

bar over which the type bands are trained at the printing line.

Fig. 6 is a perspective view of the band wheel supporting shaft on a reduced scale.

In the drawings 10 designates the casing The casing is made up of two like members 12, 12, preferably stamped from sheet metal. Each of the said members comprises end pieces 14*, 1 1, a side piece 15 and a top piece 16, and in the assembled casing the edges of the end and top pieces abut, as shown in Fig. 2.

17 designates the type wheels over which the type bands 18 are trained, said type wheels being mounted to rotate on the usual fixed shaft 19 which extends through registering openings in the type wheels and into the end walls of the shell or casing. 20 designates the bridge piece or bar over which the type bands are trained at the printing line and which extends between and is connected at its ends to the end members of the inclosing casing. Said type wheels are provided with notched flanges 21, and the members of the shell are provided at their sides with slots 22 outwardly through which the flanges extend for engagement by the fingers of the user.

The top pieces 16 of the shell members are provided with inwardly extending lugs 23 provided with apertures 24: and which, in the assembled stamp, overlap, as shown in Fig. 3. To one of the apertured lugs 23 is attached, in any suitable manner, as by solder, a screw 25 which is screwthreaded into the hand piece 11. The end pieces of the shell members are provided at their lower ends with pointed lugs 26, 26 of generally triangular form with the straight edges of the projections in line with the inner edges of the said end pieces. The said end pieces are also provided in line with the type band wheel shaft 19 with notches 27 which register when the end pieces are broughttogether in abutting relation, as shown in Fig. 2, to provide openings to receive the shaft 19. The shaft 19 is provided at one of itsends with an annular notch or groove 28 which, when the shaft is in place, is interlocked with the edges of the registering recesses 27 which form an opening to receive the shaft, whereby, when the parts are assembled, said shaft is interlocked to the shell.

The bridge bar 20 is provided with the usual upstanding flanges 30 to stiffen the same and to afford with the bridge bar smooth surfaces about which the type bands are trained. Said bridge bar is also provided at its ends with upstanding lugs 31 which fit outside of the ends of the shell or casing and is provided just inside of said lugs with apertures '32, as shown in Fig. 5.

In assembling the stamp, the screw 25, which may be an ordinary wood screw, is fitted on and soldered or otherwise fixed to-one of the apertured lugs 23. Thereafter the type band wheels and type bands are assembled and the bridge bar 20 is then placed within the lower loops of the type bands and is fitted to one of the casing members with the pointed projections 26 of the shell member engaged in the apertures 32 of the bridge bar. Thereafter the apertured lug 23 of the other'casing memher is threaded over the screw 25 and is fitted to the companioncasing member with the projections 26 thereof extending into the apertures 32 of the bridge bar, whereby the bridge bar is interlocked tothe shell. Thereafter the shaft 19 is inserted through the apertured end pieces and the apertures of the band wheels with its annularly grooved end engaged with the edges surrounding the hole in one of the ends of the casing or frame. Finally the hand piece is screw-threaded down over the screw 25 which serves, in connection with the interlocking connection of the bridge bar with the shell members, to lock the parts together. The tapered edges 35 of the projections 26 serve as wedges which act against the edges of the apertures 32 of the bridge bar to force the edges of the end piece 14 of the easing into close abutting engagement, as indicated inv Fig. 2.

When the parts are thus assembled the notched flanges 21 of the type band wheels are exposed through the slots 22 of the casing for engagement with the fingers, whereby the wheels and the hands may be adjusted to compose the type at the printing line. 7

It will thus be seen that the construction described provides means for preventing the contact of the inked type bands with the fingers or objects on which the stamp may be placed. ;The construction also provides a very economical means of constructing and assembling the stamp and produces a very strong and durable structure after the stamp is assembled.

It will be understood that the structural details shown in the drawings and described in the specification may be varied within the spirit and scope of the claims hereto attached, and that it is the intent to claim all of inherent novelty described in the specification and shown in the drawings.
